I walked past the old mosque in Kano (northern Nigeria), many moons ago. The emir was a powerful man in those days. I remember the days of the revolt led by Maitatsine in the center of that very same old Kano.
The Nigerian novelist Ukamaka Olisakwe writes about those days of old (but still very new and present) of growing up as a christian girl in Kano. The sectarian violence. She compares those days to the times she lived more to the south in her married days.
